MCQ

4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days, will 10 women complete it?

• 35 days

• 40 days

• 45 days

• 50 days

#### Solution

40 days
Explanation:
Let 1 man's 1 day's work = x
1 woman's 1 day's work= y

Then, 4x+6y=1/8and3x+7y=1/10

On solving these two equations, we get

x=11/400 and y=1/400

∴ 1 woman's 1 day's work = 1/400

⇒ 10 women's 1 day's work = (1/400xx10)=1/40

Hence, 10 women will complete the work in 40 days.
